forwardly and upwardly in order to prov mote rapid circulation. Y t

A further vobject ofthe invention is the provision of a device in the form of a grille for supplying air to a rooin,and in which the supply pipe o1' heating medium is supported on the device while the return pipe is located within the same in order that not only certain pipes will be properly concealed in the room but that a great! deal of the heat which is ordinarily lost will be employed for'increa'sing the temperature ofthe incoming air.

A still further object of the invention is the provision of a grille for supplying air to the room and which will act as a nozzle for forcing the air diagonally across the rooni and also provide a supportrfor a radiator through which the air is directed before being admitted to said rooni.

This invention will be best understood from a. consideration of the following cletailed description, in view of the accompanying drawings forming a part of the specification; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient feature of the invention as expressed in the appended claims.

In the drawings y Figure 1 is a vertical section of the grille in the approved form of ymy invention,

Figure 2 is a vertical section of the rgrille shown in Figure 1, and in which the supply and return pipes of a heating system are carried by the grille, y Y

Figure 3 is a vertical section of the grille shown in Figure 1 with provision for supporting a radiator and shield,

Figure 4t is a vertical section showing the grille and radiator and shield in elevation,

Figure 5 is a view in perspective of the grille 'I constructed according to the principles of my invention, y

Figure 6 isa vertical section taken along the lines 6-6 of Figure 4, and

Figure?" is a vertical section of a Inodilied `forni of the device showing the radiator and shield supported above the grille by the wall of the rooin.

Referring more particularly to the drawings, 10 designates the wall having a duct 11 below the floor 12 to which. fresh air is supplied by means of a blower. The floor is rovided with an elongated opening 13 adjacent the wall 10 and below a grille 14 which is constructed in accordance with the principles of my invention.

' The grille has a rear wall 14, and a front wall 15 which is inclined towards the rear wall and of less height thansaid rear wall,

theinclination of the front wall restricting the discharge opening-16 so that in effect al nozzle is provided whereby the air forced from the mouth of said grille will not only tend to travel outwardly and yupwardly along the diagonal of the room, but will have its velocity increased. End walls 17 connect the front and rear walls, and a flange 1S is provided having perfor-ations which secure the grille to the licor of the ro'orn. It will be noted that the flange 18 is formed along the front and end walls. lnclined ribs or bars 19 connect the upper edge of the front wall 15 with the rear wall and at points along the rear wall which are adjacent the upper edge 20 of said wall. order to facilitate the properr fection of movement of the air, asindica ed by the arrows in Figure 1, the upper inner face 21 of the front walls 15 is curved slightly outwardly.

Referring more particularly to Figure 2,v the grille is 'identical in construction with the grille shown in Figure'V 1 but I have eniyployed the grille in this case to not only support a supply pipe 22 for a heating system, but for enclosing a return pipe Q3. The supply pipe is provided' with the usual clamping means which are connected with bolts 24. These bolts are adapted to he threaded into pei'crations formed in the upper end ci the front wall l5 of the grille lili as will be presently described `with reference to the construction shown in Figures 3 and 6. lt will be appreciated that the size or the grille shown in Figure; 2 may be reduced and the slats or ribs 19 may be dispensed with if desired so that the grille in this case serves a double purpose for concealing the return steam pipe 23 and for carrying and supporting the supply pipe 22, and alsoifor locating the stcain pipe at a conyiinient place along the wall near the floor line ci the room, and such grille may be employed for housing and supporting hot steam pipes while also providing a means tor supporting a radiator. rllhis form ot grille in connection with the supply and returnr pipes is particularly adapted `for use in heatingy the basement rooms of a building.

Referring more particularly to liigures 3, l and 6, a grille la is similar in all respects to the grille shown in Figure 2, since in both casos the upper end'o't the iront wail 25 is enlarged as shown at 26 to providembosses having internally threaded passages 2'? adapted to receive bolts 28, these bolts are adapted to receive by-passages i'orined in radiator supports 2l). These supports run longitudinally ci the upper edge ot the iront wall of the grille for the length of the radiator, and the radiator is secured in any approved manner to the supports 29. ln such a case, a grille is secured to the floor l2 and heated air is iiorced between the walls 25 and 30 ci' the grille to the open end or nozzle 3l, past the grille bars or slats 32, then upwardly and through the spaces between the vertical sections 33 of the radiator 34. As the air is forced through the sections of the radiator, the air is caused to whirl and provide for the proper diffusion of the heated air in the room, and dormant air which is associated with or in close contact with the radiator is placed in circulation so that the greatest eiiiciency is had 'for the heating system.

ln order to torce the air upwardly and over the surface ot the radiator, it may be advisable in some instances to employ a shield which is connected by ll-shaped brackets 35 and 86 to the radiator by means of bolts 37. This shield prevents the heat troni being forced directly forwardly 'from the radiator and thus protects the person sitting near the radiator from the direct contactwith the heated air and also the heat oi' the radiator, since the air is directed upwardly and away from the'radiator. The shield generally designated by the numeral 38 has an outside facing 39 formed oit sheet steel, while the inside portion is faced as shown at 4i() with asbestos mill board or other suitable insulating material. The shield, as shown at l-l, is bolted directly to the outside iiange of the brackets and 36. ln the inodilied form shown in liligure Y, the radiator, instead oi being supported upon the iront wall l5 of the grille 14, is

connected by means of bolts to the wall.

l() of the room7 and a sleeve i3 on said bolts aids in spacing the radiator trom said wall. 38 in spaced relation with said radiator. ln this construction the air, as has been stated, is preliminarily heated and is torced'through the passage ist of the grille 14 up through the nozzle 16, then upwardly vbetween the wall andthe radiator through the radiator and'tlien battled by the shieldBS so that the air willbe directed upwardly and away trom the radiator, as has been described relative to the construction shown in liigure 6.

Since the air is supplied by fa blower -tlirough the grille and past the radiator on the pipes 22 and 23'the air is heated more rapidly, dueto the fact oflthe higher speed of the air wheny comingin contact with the surface portions of the radiation.

What l claim is 1 l. ii heating device comprising a grille having a rear wall, a front wall inclined to wards the rear wall and or' less height than the rear wall, end walls connectingV thefront and rear walls, the upper and lower ends of Brackets and 56 support the shield ice wards the rear wall and of less height than the rear wall, end walls connecting the front and rear walls, `the upper and lower ends of the grille being open, bars connectingthe upper edges of the front wall wi'th'the rear wall, and inclined at an angle toy thel hori-v zontal, and a radiator carried by the `front wall of the grille. Y
